The short answer is no. The Bourne and Sagamore work the way they always have. Real construction at the bridges does not start until the winter of 2027 and 2028. Until then, plan your Cape trip the same way you would any year.
The quick answer
- Summer 2026: nothing changes. Same bridges, same lanes, same routes onto the Cape.
- Summer 2027: still mostly the same. Designers are finishing plans. Equipment may start staging off the bridges.
- Summer 2028 and later: workers are building the new Sagamore next to the old one. The old bridge stays open the whole time.
What you’ll actually see this summer
- Same Sagamore Bridge. Same Bourne Bridge. Same lanes. Same shared-use paths along the canal.
- A few maintenance lane closures, the kind that happen every year on US 6.
- No detours, no major work zones, no construction equipment at the bridges themselves.
What about traffic?
Cape traffic is Cape traffic. Friday afternoons heading onto the Cape, Sunday afternoons heading off, holiday weekends. None of that changes because of the rebuild.
The MassDOT advisory feed shows live lane closures on our Crossing the Canal page if you want to check before you head out. Apps like Waze and Google Maps work fine. Use whichever you usually use.
Should I avoid the Cape this summer because of construction?
No. There is nothing to avoid yet. Some travelers worry that confusing news about the bridge replacement means the Cape is not a good summer trip right now. The bridges are open. The roads are open. Hotels, beaches, restaurants and ferries all run like normal. Go.
When should I start paying attention?
Late 2027 onward. By then, construction equipment will be at the Sagamore and we will be running weekly updates on what changes and when. Until then, the project is happening on paper and in office buildings, not on the bridges.
